State and territory border closures have been a key part of Australia’s COVID-19 management plan. At some point during 2020, Victorians were locked out of every state and territory (apart from the Northern Territory) and required special permission to cross those borders.

The Victorian government has also used border closures to manage outbreaks in other states. Victoria closed the border, at various occasions, to Queensland, Western Australia, South Australia and New South Wales in 2020 and 2021.

This chronology has been put together using state and territory media releases from Premiers, Chief Ministers and Health Ministers, information from state and territory Health Department/Coronavirus websites and media articles where Premiers/Chief Ministers or Health Department officials are quoted.
